  • True or False: The rock cycle only involves igneous and sedimentary rocks, not metamorphic rocks.
    False (The rock cycle includes all three types of rocks: igneous, sedimentary, and metamorphic.)
  • True or False: Granite is an example of an igneous rock that cools slowly underground.
    True
  • True or False: Sedimentary rocks can only form on land.
    False (Sedimentary rocks can also form in the ocean from sediment like shells and mud.)
  • True or False: Igneous rocks can only form above ground.
    False (Igneous rocks can form both above and below ground.)
  • True or False: Shale is a sedimentary rock formed from mud.
    True
  • True or False: Igneous rocks form when hot, liquid rock cools and hardens.
    True
  • True or False: Metamorphic rocks are formed when rocks are changed by heat and pressure deep within Earth.
    True
  • True or False: Sedimentary rocks are formed from sediment that comes from the weathering and erosion of larger rocks.
    True
  • True or False: Pumice is denser than basalt.
    False (Pumice is light and airy, while basalt is denser.)
  • True or False: Heat and pressure can turn sedimentary rocks into metamorphic rocks.
    True
  • True or False: Metamorphic rocks are usually softer than sedimentary rocks.
    False (Metamorphic rocks tend to be harder.)
  • True or False: Limestone is a sedimentary rock formed from the shells of tiny organisms in the ocean.
    True
  • True or False: The rock cycle describes how rocks are created, destroyed, and recycled on Earth.
    True
  • True or False: Slate is a metamorphic rock formed from shale.
    True
  • True or False: The minerals in igneous rocks that cool slowly underground form large, visible crystals.
    True
  • True or False: Marble is a metamorphic rock formed from shale.
    False (Marble is formed from limestone.)
  • True or False: The stripes or swirls in metamorphic rocks are caused by the melting and flowing of different-colored parts of the rock under pressure.
    True
  • True or False: Weathering and erosion break down rocks into sediment.
    True
  • True or False: Basalt and pumice are igneous rocks that cool quickly above ground.
    True
  • True or False: Earth’s plates play no role in the rock cycle.
    False (The movement of Earth’s plates helps rocks sink into the mantle and melt, which is part of the rock cycle.)
